The uniform circular disk of 4-in. radius and small thickness weighs 8 lb and is spinning about its y′- axis at the rate N = 300 rev/min with its plane of rotation tilted at a constant angle β = 20° from the vertical x-z plane. Simultaneously, the assembly rotates about the fixed z-axis at the rate p = 60 rev/min. Calculate the angular momentum H_O of the disk alone about the origin O of the x-y-z coordinates. Also calculate the kinetic energy T of the disk.
